help for embedded ethernet

hello everyone

i am planning a project on an embedded server for applications like temperature monitoring and interdevice communication and want to interface a ethernet controller with a 8051 based microcontroller.

searching on the net i found certains options as :

1. c58900A ethernet LAN controller
2.RTL 8029AS/ RTL 8139C
3.using the Zilogs Z80Acclaim! Flash microcontrollers that have and onchip ethernet MAC 10/100 BaseT
4. Microchips ENC28j60 (stand alone ethernet controller with SPI interface) that can be interface to a flash mcu
5.LAN 91C111 10/100 Non PCI ethernet single chip MAC + PHY

frankly i donot have much idea about these and have never worked on networking applications .

what are the various ways of interfacing a microcontroller to an LAN/WAN?

please help me out with my project and suggest any material that i can read regarding the same.
thanks alot

Their is nothing to panic about ur project .. its really a good one
the Z80 is a very good muC .. but the development boards are expensive...
instead there are other cheap 8051 based Web server.... try Rabbit core boards which come with helluva stuff with it..


a Web server is nothing but a huge c program with implements a TCP/IP stack and gives a API to user for using the TCP IP services .... The mu C will be interfaced to a Ethernet Phy chip which takes care of all the Physical layer activities ...

cude !!! frankly u need to study a lot in internet .. search for some existing Web server for DAQ projects and extract ideas...

or just put ur specific questions to this forum

hope i helped

check out this post

There is something called the ETHERNUT project which has implemented something close to your project, but with AVR ATMEGA uC, chech it out over the internet, it has the TCP/IP and the web server implemented in C.

try

MC9S12NE64

this is a freescale micro;

attach magnetics and you done sollution.

I make a similar project using at89s8252 and Digi-One ethernet modulem in this link below you have many options about ethernet embedded
